Fire department personnel rushed to the site after receiving a call from police requesting an ambulance for a man in his 40s who was bitten by a dog at the park in a residential area of Isezaki city in Gunma prefecture, about 100 kilometers (60 miles) northwest of Tokyo.

Nine of the attacked people were children aged 7 to 10 and the 10th victim was an adult, the Isezaki fire department said.

Most of the victims were bitten in their legs, it said. Several were taken to a hospital for treatment.

The department said police caught the dog and were investigating the case.
